Pro Dose Equipment

Syringe Unit Calculator

Work out how many units on a U-100 syringe match a given volume. Enter what's in your vial, how much diluent you added, and the dose you've been prescribed — this page does the arithmetic and shows you where it lands on the barrel.

As printed on the vial label.
mL
The volume of liquid you put into the vial.
The dose your prescriber gave you. We don't recommend doses.
U-100 means 100 units per 1 mL.

This is a measurement tool, not medical advice. It converts figures you enter into a volume and shows where that volume sits on a syringe barrel. It does not recommend doses, diluent volumes, compounds or administration methods — those are decisions for you and your prescriber. Pro-Dose Equipment supplies equipment only.

Always confirm your dose against your prescriber's instructions and the product's instructions for use. If a result here disagrees with either, trust them, not this page.
